The Role

• Leverage HTML, CSS, and JavaScript to assess and creatively solve integration issues on merchant websites and in-store terminals
• Maintain comprehensive integration documentation following established templates
• Operate within and contribute to the team's established operating rhythm, including regular merchant health reporting, portfolio reviews, and performance measurement against defined KPIs
• Document challenges and blockers encountered to share learnings with other Technical Account Managers in stand-ups and status check-in calls
• Participate in on-call incident response rotation with SLA adherence, contributing to end-to-end incident management including RCA delivery and senior leadership communication
• Leverage AI and automation tools to improve efficiency in merchant analysis, issue detection, documentation, and portfolio management
